Gordon Strachan is to court controversy with his first squad as Scotland's manager by naming Rangers' Lee Wallace in the party to face Estonia at Pittodrie.

Strachan will unveil his maiden squad at a press conference in Aberdeen at Thursday lunchtime. Included in the group will be the 25-year-old Wallace, despite Rangers' current position in Scotland's Division Three.

Wallace has six international caps and has been a consistently impressive performer since breaking through as a teenager at Hearts. His position, left-back, is also a troublesome one at present for Scotland's national team.

However, an element of the Scottish support will inevitably question why a player who performs in the domestic game's lowest professional tier should be worthy of an international place.

Craig Levein, Strachan's predecessor, said it would be "difficult" to pick Rangers players but did hand one of them, Ian Black, a late call-up for a friendly meeting with Australia. Black was booed when he appeared as a substitute in that game.

The Estonia fixture is Strachan's only non-competitive match before he begins his quest to haul Scotland from the bottom of their World Cup qualifying section. The Scots face Wales and Serbia in March.
